Original application filed May 16, 1925,

buckling and sometimes torsional stresses.

5 Said parts are made of one or more metallic plates or panels formed with or bracing means to resist such While efforts are made to block the lading in the car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the end of the car, thelateral weaving of the car throws it, against the side of the car, and the impact throws it against the bottom of the car. My invention is adaptable to box, gondola or other types of cars.

One of the objects of the invention is to. provide metallic parts of a railway car which have great strength to resist the torsional and weaving stresses which exist in a railway car when moving in service. ,These stresses are caused by the inertia of the roof 5 and superstructure when the train is suddenly stopped; rough or uneven tracks; the superelevation of the track on curves; the lateral inertia in rounding curves; eccentric thrust due to the lading beingsecured to one side of the car; the cars being.cornered; the use of push pole pockets, etc, Such stresses rack and distort the superstructure which decreases the life of the car, and also causes the car to leak grain, sand, and other such material. Furthermore, such stresses cause leaky roofs and leaky and inoperative side and end doors. 7

The tendency of'an all metal end wall to bulge is resisted partially by the corrugations, stiffening members or whatever means have been provided to transmit such stresses to the side wall or frame members of the car. Such tendency is also resisted by the corner post of the'car acting as a vertical beam supported at its top and bottom and V sustaining a horizontal load; in other words, the bulging of the end would pull the opposite corner posts toward each other. This bulging also tends to pull the end (or side) plate downwardly and the end (or side) sill upwardly. Anotherobject of the invention is to reinforce or supplant the frame members against thrust perpendicular to their length y means form ng part of a c neening stresses.

lt hasbeen proposed to press the central portion of a metallic plate (or plates) so as to form a continuous web or flange surrounding a panel and to reinforce this panel by horizontal corrugations or other integral reinforcements which traverse the panel and terminate adjacent the opposite portions of the web or flange. In such an arrangement the load upon the horizontalcorrugations for is transmitted to the continuous web flange only through the intermediate means of the, flat portion of the plate lying between the end of the horizontal corrugations and continuous web, or flange. It has also been proposed to press the central portion of a metal plate. (or plates) so as to form a web or flange (supposedly) surrounding a panel. and to reinforce this panel by horizontal corrugations or other integral reinforcements which are the same depth as the web or flange where they merge into it. In such an arrangementthe web or flange as a beam is destroyed. In my construction thetransverse corrugations destroy only a part of the valueof the web, leaving a remaining portion which extends continuously around the panel to receive the stresses from the horizontal corrugations and tofunction as a beam and a stiffener. Such stresses are transmitted directly to the remaining portion of'the web. V

- The corner post of an ordinary box or gondola car performs two functions; first, as a compression member of the truss forming the side frame of the car, and, secondly, as a vertical beam receiving the loads from the several horizontal frame members of the end wall and transmitting them to the side wall of the car The end: plate of a car is the and m mber if the r ef framing trum ture and the end sill is the end member of the underfraine and as such performs sin1ilar functions to the corner post. Also the end plate and the end sill are horizontal beams receiving the loads fromthe end wall and transmitting them to the roof structure and underframe, respecti in the specification and in the claims forming'a part thereof the term fraine'member j means either the corner post, end plate, end" shifting loa'dand transmit them tothesurrounding corrugation which is preferably positioned adjacent" the frame member or members. This surrounding co'rrup may be desi ned to reinforce the existing frame member of a c'arlor to (to-operate with another part of the car to perform the functions of the frame member or may be designed to independently perform the function of the frame-member and thus constitute the frame member itself.

In my con'struc'tionthe central portion of the metallic plate 1 (of plates 1 '-2')' is pressed to form a continuous corrugation 3 surrounding a panel 4, Which corrugation comprises an inner Wall. 5-6 andan outer Wall 78 and is preferably positioned adjacent the outside edges of the plate or outside edges of the Wall Whether the Wall is made of one or more plates. i

The panel 4 is reinforced with corrugations 9 or integral ribs which traverse the panel and merge into a part of the" opposite portions 55 of the inner Wall of the continuous corrugation, leaving a remaining portion 1 0 of the inner Wall which extends continuously and uninterruptedly on three (or preferably four) sides ofthe panel. The inner Wall 5 receives the load from the transverse corrugations 9 and in combination With the outer Wall 7 of the continuous corrugationforms a beam or a stiffener to prevent bulging in transmitting the load from the transverse corrugation-s to the can, The inner Wall 5 and outer Walls 7 of the vertical portion of the continuous corrugation are prevented from buckling or deflecting by be ing connected to the horizrontal' portions 68 of the corrugations by the (preferably) radial portions 11 12 Which thus form a continuous or unending corrugation. q

The transverse corrugations] may be made the'same' d'epthor a greater depththan the v depression forming the continuous corrugationbut th-ejcorrug'ations are: of less depth than t-he'walls 5 -5 Where the mergeintdit.
